McFeggan Brown

McFB Invoice Stamp

Stamp an invoice as approved or rejected without leaving Outlook. Open the email, click Stamp Invoice, add your name and a note, then reply with the stamped copy attached.

Invoices are read and stamped on your own computer. They are never uploaded anywhere.

Add It to Outlook (One Time)

  1. Download the add-in file: mcfb-invoice-stamp.xml.
  2. Go to aka.ms/olksideload and sign in with your McFeggan Brown account. Outlook opens with the Add-ins for Outlook window.
  3. Choose My add-ins. Under Custom add-ins, choose Add a custom add-in, then Add from file.
  4. Pick the file you downloaded and choose Install.
  5. Restart new Outlook. Open an email with an invoice attached and look for Stamp Invoice in the toolbar (it may be under the Apps button or the … menu).

If “Add a custom add-in” is missing, your Microsoft 365 administrator has turned it off. They can add the same file for everyone in the Microsoft 365 admin centre under Settings › Integrated apps.

Not Using Outlook?

Open the stamp tool in your browser and drag in a PDF or Word invoice saved on your computer.
